My invention relates to cylinder honing By-preference, therefiare employed two tools, and has for its object to provide ahone pairs of bones, generally designated by the whichis convenient to use, easily set for numeral 8, which may be. distinguished by any size of cylinder bore, within its range, suffixes, as 3a, 3b, 3c and 365. These are arin which the several house can be adjusted, ranged in pairs, 3a and 3?) being the coarse the hones of'each pair simultaneously, indepair, for instance, and 3c and 30? being the pendently of the other pair or pairs, and by fine'pair, although itwill be-understood of like amounts, or'in which all hones can be course, that all might be ofglike texture; one adjusted simultaneously and by like amounts, pair might be non-abrasive in character,

in and further, a hone which by reason of this serving only as a guide. These are disposed freedom of independent adjustment will enparallel to each other, and parallel to-the able the hones of one pair to be set at a slightaxis of a rotative base 1. This base issup: ly greater diameter than the bones of anothported from a live shaft by any suitable er pair, or vice versa, and maintained durmeans, such as the coupling collar 2, having 1.1 ing further adjustment at the sameidifier part of a bayonet joint, indicated at 20, with- 0 ence of diameter, so that if two pair are used in its end bore 21, and supporting the base the coarse pair may be set out farther at first 1 by; means of a connecting stub shaft 22, and the fine pair may be employed as guides, forming in effect an axial extension of the to prevent sticking and chattering, and final base 1, being threaded therein at 23 The an ly in finishing the operation, the liner pair coupling collar 2 is pinned to the shaft 22, 5'

To accomplish dinal section, substantially onthe line 5-5 these ends, each sleeve may be formed with V 45 of Figure 4E.

worm or skew gear teeth 54, and meshing V 9:

with these teeth are complemental teeth 45 upon the respective shafts 4. Internally, the sleeve is threaded and bolts 30 and 31 project inwardly from the respective hones to engage within these threads in the sleeve,

as may be seen in Figure 3. Preferably, and i in order to give greater flexibility and a wider range of adjustment, one of thesupporting bolts, as 31, is formed of greater diameter than the bolt 30, though both are alike in pitch, and the larger'bolt 31 is axially bored or recessed in its inner" end, as

. indicated'at' 32, whereby the inner end of the smaller bolt 30 may project within the recess 32.

Rotation of (see the" shafts" 4; willj'cau se rotation of the two sleeves 5 with which its gears 45 are meshed. Rotation of these sleeves, one at the top and one at the-bottom of the base 1, will cause projection or retraction of the pair of diametrically opposite, .h'ones supported from these particular sleeves. The hones move inwardly or out vwardly simultaneously, and by like amounts,

since-the pitch of their supporting bolts 30 and 31 is alike; Rotation of the outer shaft, 40, will cause rotation of the sleeves 5 which are in mesh with thisgear, and corresponding projection or retraction; of the hones which are supported from these sleeves, the homes being preferably arranged at; ninety degrees to the first pair of hones.

Preferably, the two shafts 4 and 40 may be independently rotated, and to enable this and to hold' the shafts in place in the base, I providea head 44 securableupon the upper end of each shaft above the base '1, and this head maybe received between collars 25 and 26 upon the shaft 22, being heldin place upon its shaft 4' or 40 by a pin 43 (see Figure 3). This head may be knurled, and thus the shaft 1 to which it is connected may be rotated.

At times it is desirable to adjust all of the hones simultaneously and by like amounts, and to enable this to be accomplished, I provide'a pinion 4 6or 4T upon'the upper end ofl'each shaft 4 and 40 respectively, and a v third or driving pinion 6 is supported'upon a'collar 60, whichis slidable axially of the shaft 22, so that it'may engage both of the pinions' 46 and 47, or may be disengaged from 0th of them. When engaged both shafts are turned simultaneously and in like amounts, maintaining throughout such adjustment anyeXisting differenceof setting,

and consequently all hones are projected or retracted simultaneously and equally. The collar 'may be secured in. operative or in inoperative position byJtheengagement of a'spring-pressed follower 61 within one of two grooves 27 and 28 (see Figure in the shaft22. Y The shape, size and precise manner of support of thehones is largely immaterial. As

herein shown, each is held "in achann el 33,

one side of which is slightly inclined, and a wedge 34 is forced into place by a screw 35 to clamp the hone into its channel. Any suitable means to accomplish the purpose may be employed.

As is seen in Figure 4, the fine hones, 30 and 3d, are projected to the outer circle C,

whereas the coarse hones, 3a and 3b, are projected only to the inner circle A. These circles may vary by only a few thousandths of an inch, butwhile the coarsehones, 3a and 36, do not in such a situation'wear down the cylinder bore, they are nevertheless effective, since any tendency to vibrate, to chatter, or to cause the axis of the honing tool to depart from the axis of the cylinder bore will cause the slightly retracted hones 3a and 3b to bear against the wall and to act as guides to steady the honing tool so that the hones 3c and 3b may-continue to bear truly and without chattering or undue .noise.

The relative positionsof the hones, may, of'course, be varied, audit is to make such changes of relative positions possible that the independent adjustment of the pairs of hones is'provided. However, when the hones have been set with the proper-difference between their circlesA and B, all may be pro jected or retracted atone time without changing this spacing between the circles.

Rotation is in the direction of the arrow B (Figure 4). To relieve the hones from too rigid a support, without departing" from exact adjustment, the supporting boltsfor instance, the bolts 31,-Inay be slit close to l the hone, and at the rear side as the hone advances. Such a slit is indicated at 39. It

permitst-he hone to yield slightly at its rear edge, yet sufiiciently to cause it to bear always truly, and to operate without chatterdown the hone,'nor is it necessary to reset s and dress special guide members. The hones themselves, that pair" which are not at the moment working, will serve as guides for the pair whichv at the moment are Working. c What I claim as my invention is:
